'Cyber space and outer space are today's cutting-edge areas of international security concern. One critical difference between them: We have norms in place for the preservation of peace in outer space. While these norms are contested, they provide the starting place for discussion. No comparable principles exist for cyber space – at least before now. Cyber Peace takes up the nascent idea that cyber space should never become battle space. The authors provide critical, normative scholarship necessary for the complex task of building cyber governance in the interest of human flourishing.'
